When do I need to waterproof a bath?
A bath on its own - used only as a bath does not need to be waterproofed. However, if you have an over-head shower above the bath then we would recommend that you consider as how best to waterproof the installation. If you are finishing with wall panels, we would recommend that you use Classi Seal. If on the other hand you are tiling, then you have two options- Classi Plus which will waterproof between the ledge of the bath and the wall or the Classi Kit which waterpoofs this ledge as well as the walls.
